[0025] In order to make the purpose, features, and advantages of this patent more obvious and easy to understand, the technical solutions in the embodiments of this patent will be clearly and completely described below in conjunction with the drawings in the embodiments of this patent. Obviously, the described embodiments are only part of the embodiments of this patent, not all of them. Based on the embodiments in this patent, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this patent.
[0026] The paint for plowing texture effect provided in the embodiment of the present invention includes the following components by weight percentage: 1.8% to 2.2% polyethylene particles, 2.8% to 3.5% polymethyl methacrylate, 21.5% to 21.7% acrylic resin, 1% to 1.2% additives, and 44% to 53.6% ethyl acetate. The paint obtained by adding 1.8% to 2.2% polyethylene particles in the embodiment of the present invention can achieve a texture with a grain on the sprayed surface through a conventional spraying process, and can achieve the effect of plowing texture, thereby achieving the purpose of consistency in the overall appearance of the product.
[0027] In a specific embodiment, the composition further includes: 0-1% cellulose acetate, 1.7%-2% silicon dioxide, 0-1% carbon black, 10.6-12.9% titanium dioxide, 0-1% red toner, 0-1% yellow toner, 8.3-10.1% talc, and 0-1% polyethylene.
[0028] In a specific embodiment, the particle size range of the polyethylene particles is: 25μm to 35μm. When the polyethylene particles with a diameter greater than 35μm account for more than 3%, the product effect is too rough and affects the reliability of the paint, while when the diameter is less than 25μm, the texture is fine. Adding 1.8% to 2.2% of polyethylene (sand powder) with a diameter of 25μm to 35μm polyethylene particles to the paint composition and fully mixing with raw materials such as resin can ensure the uniformity of the paint spraying effect.
[0029] In a specific embodiment, the auxiliary agent includes a leveling agent and / or a defoaming agent.
[0030] The paint preparation process for the plowing texture effect provided by the embodiment of the present patent includes the following steps: adding polymethyl methacrylate and acrylic resin to a dispersion tank, starting stirring, stirring at a speed of 300-500r / min for 5-10 minutes; adding an additive to a dispersion tank, stirring at a speed of 300-500r / min for 5-10 minutes; adding polyethylene particles to a dispersion tank, stirring at a speed of 300-500r / min for 5-10 minutes; adding a solvent to a dispersion tank to adjust the viscosity and fluidity. The paint obtained by adding 1.8% to 2.2% of polyethylene particles can achieve a texture with a grain on the sprayed surface through a conventional spraying process, and can achieve the effect of a plowing texture, thereby achieving the purpose of consistency in the overall appearance of the product.
[0031] In a specific embodiment, the method further includes the steps of gradually adding the pigment into a dispersion tank to mix the pigment and the solvent into a slurry, stirring for 10 to 15 minutes to uniformly disperse the pigment in the paint.
[0032] In a specific embodiment, a solvent is added to a dispersion tank and stirred for 5 to 10 minutes to adjust the viscosity and fluidity of the paint.
[0033] In a specific embodiment, the gloss of the paint can be adjusted by adding a gloss body to the dispersion tank.
[0034] In a specific embodiment, the amount of polyethylene particles added is recorded as 1.8% to 2.2% by mass, and the particle size range of the polyethylene particles is: 25μm to 35μm. When the polyethylene particles with a diameter greater than 35μm account for more than 3%, the product effect is too rough and affects the reliability of the paint, while the texture is finer when the diameter is less than 25μm. Adding 1.8% to 2.2% of polyethylene (sand powder) with a diameter of 25μm to 35μm polyethylene particles to the paint composition and fully stirring it with raw materials such as resin can ensure the uniformity of the paint spraying effect.
[0035] The third aspect of this patent provides a plowed texture spraying process, using the paint for the plowed texture effect provided by the first aspect, or, using the paint prepared by the paint preparation process for the plowed texture effect provided by the second aspect.
[0036] The existing SIM Tray molding solution cannot meet the requirements of the plowing texture appearance because:
[0037] 1. Sim tray is made of stainless steel powder and paraffin by injection extrusion. If there is a texture on the mold, the pattern will be destroyed during sintering, shaping and magnetic polishing.
[0038] The existing process includes: injection sandblasting, degreasing, sintering, shaping, magnetic polishing, PVD spraying, full inspection and packaging. During the sintering process, the surface of the SIM Tray product will become flat at 1200°C, thus damaging the texture. During the shaping process: the product will be deformed due to the high temperature during sintering, and the texture will be further damaged by extrusion shaping using 30T shaping equipment. The surface finish will be improved and the precision will be improved during the magnetic polishing process, and the texture will be damaged again.
[0039] If the product is sandblasted after magnetic polishing, so that the surface has a plowing texture effect, there will be quality problems if it is sprayed at the end. For example, the process includes: injection sandblasting degreasing sintering shaping
[0040] Magnetic sandblasting, PVD spraying, full inspection and packaging. The sandblasting process has high precision control to avoid excessive dimensional changes or damage to the product surface. In the spraying process, the SIM Tray will have quality problems such as paint accumulation and fat edges after painting, as well as the risk of texture being covered.
[0041] If the product is sandblasted after magnetic polishing, and then the surface treatment is changed from painting to PVD, it will be difficult to adjust the color when chasing the C cover color, and the cost is high. For example, the process includes: injection sandblasting, degreasing, sintering, shaping, magnetic polishing, PVD, PVD, full inspection and packaging. In the PVD process, it will be difficult to chase the color and the PVD cost is high (the PVD color in step 7 is not required, and it mainly plays the role of internal structure insulation)
[0042] In the embodiment of this application, on the basis of the existing color coating, 1.8% to 2.2% of polyethylene particles (similar to the effect of fine sand, about 25μm to 35μm) are added, and the texture of the sprayed surface is achieved through our conventional spraying process to pursue the effect of ordinary plowing texture, thereby achieving the purpose of consistency in the overall appearance of the product. This application is based on the metal primer and contains 25μm to 35μm polyethylene particles in the resin, so that the coating film has a multi-layered visual sense and feel, and is more coordinated with our textured products.
[0043] This application can achieve the effect of spraying on the surface of the SIM Tray, which is visually and tactilely similar to the textured board signed by the customer. According to the debugging proofing verification, when the fine sand with a diameter greater than 35um accounts for more than 3%, the product effect is too rough and affects the reliability of the paint, while the texture is finer when the diameter is less than 25um. Add 1.8% to 2.2% polyethylene (sand powder) with a diameter of 25μm to 35μm to the paint composition and stir it thoroughly with raw materials such as resin to ensure the uniformity of the paint spraying effect. The plowing texture spraying process provided in this patent embodiment includes: injection
[0044] Sandblasting, degreasing, sintering, shaping, magnetic polishing, PVD spraying, full inspection and packaging. The disclosed embodiment adjusts the paint composition to increase the degree of roughness and compensate for the problem that the PU paint has a delicate appearance and is abrupt with other textured parts. Generally, PU paint has a relatively simple and delicate composition, and the flat surface has no feel and no obvious particularity. The paint for the plowing texture effect provided in the disclosed embodiment is evenly distributed in the resin through polyethylene particles with a diameter of 25μm to 35μm, so that the coating film has the texture of ordinary plowing texture.
[0045] The following table compares the effects of the paint for plowing texture effect provided in the embodiments of the present disclosure with the paint without polyethylene particles:
[0046]
[0047] The actual measured comparison of the roughness of the paint for the plowing texture effect provided by the embodiment of the present disclosure and the standard texture board is as follows:
[0048]
[0049] The above two tables are to show the difference between the current paint color palette containing fine sand and the color palette without fine sand in comparison with the digitalization of the textured board BM-H2 / BM-DS02 in the notebook industry. From the table, it can be seen that the current imitation fine sand color palette will be more coordinated in visual effect when paired with BM-H2 / BM-DS02 than the other one.
[0050] BM-H2 and BM-DS02 are two types of texturing (a common surface treatment in 3C - texturing). Yes, it is to achieve a more coordinated matching of plastic parts with texturing. From the above process, it can be seen that the SIM tray is made of stainless steel powder by injection extrusion, and the process does not allow texturing. In terms of application, as long as the small parts are processed by injection, sintering, etc. with stainless steel powder, this method can be used to match the texturing of large parts, making them more concise, unified and coordinated visually.
[0051] It should be understood that the various forms of processes shown above can be used to reorder, add or delete steps. For example, the steps recorded in this patent can be executed in parallel, sequentially or in different orders, as long as the expected results of the technical solution of this patent can be achieved, and this document does not limit it here.
[0052] In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of this patent, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.
[0053] The above are only specific implementations of this patent, but the protection scope of this patent is not limited to this. Any technician familiar with this technical field can easily think of changes or substitutions within the technical scope disclosed in this patent, which should be covered by the protection scope of this patent. Therefore, the protection scope of this patent should be based on the protection scope of the claims.
